Specification of Letters Patent.

To all whom it may concern:

Be it known that I, EMIL MARSOI-INER, a subject of the Emperor ofAustria-Hungary, reslding at Grosspriesen, Austria-Hungary, haveinvented new and useful Improvements in Devices for Holding Thrums orKnotting- Threads in Looms, of hich the following is a specification.

The present invention has for its object a device whereby the thrums orknottingthreads required in the working of a loom are always held flatand parallel to each other within readily convenlent reach of theoperator, so that when a knotting-thread is required it can be drawnfrom the right or left or even from the middle of the device withoutdisturbing the other knottingthreads in the slightest.

The improved device has two springclamps adapted to be arranged on theoverlay-beam of the loom, each clamp consisting of a leaf-spring and twocurved springs arranged one on each side of the leaf-spring, so that thelatter can play freely between them, the three sprin s of each clampbeing connected with eac other at one end, but being free at the otherend. For the purpose of facilitating the mounting, removal, and shiftingof the spring-clamps they are arranged on sheet-metal strips which catchunder and over the overlay-beam and are clamped against the lower flangethereof by springs.

The accompanying illustrative drawings show one construction of theimproved device, Figure 1 being a side elevation, and Fig. 2 a frontelevation thereof.

To the usual overlay-beam 1 of the loom are secured two spring-clamps ata suitable distance from each other, each of which consists of areversely-curved leaf-spring 2 and two curved springs 33, arranged oneon each side of the leaf-spring 2, so that this latter can move freelyto and fro between the two curved hook-shaped springs 3, Fig. 2.

The knotting-threads, which lie flat and parallel to each other, arelaid in between the springs 2 and 3, for which purpose the free ends ofthese springs are adapted to be pressed inward or outward, as shown indotted lines in Fig. 2. The ends of the bundle of knotting-threads arelaid transversely to the longitudinal direction thereof, as

shown in dotted lines in Fig. 1, through the dle parts of which lie freebetween the springclamps, can then be seized at one end or the other oreven at the middle between the two spring-clamps and simply drawn outwithout disturbing the remaining threads of the bundle in their parallelposition or appreciably shifting them in the spring-clam s. Thesespring-clamps may be attached to t he overlay-beam of the loom invarious ways, conveniently, for example, in the manner shown in thedrawings, where the clamps are arranged on sheet-metal strips 4, whichlie against the lower flange of the overlay-beam and catch with theirrear turned-up end 5 behind the web of the beam and are clamped againstthe lower flange of the beam by springs 6, which bear against the upperside of the lower flange and against the front of the web of the beam.The sprin s 2 3 6 may be conveniently constructed of s eet metal. Thismethod of attaching enables the springclamps to be easily mounted andremoved and conveniently adjusted to suit the length of theknotting-threads desired.

The present device, while exceedingly cheap to construct, effectivelyholds the knotting-threads always within convenient reach of theoperator, and thus renders the attendance of the loom easier, so thatthe output is augmented. Moreover, it is ver easy to charge the devicewith the desired threads.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. A device for holding knotting-threads comprising apair of cooperating springs forming a clamp adapted to be mounted on theoverlay-beam of the loom and between -which spring the knotting-threadsare held,

each other at one end, but being free at the other end, substantially ashereinbefore described.

3. A device for holding knotting-threads comprising spring-clampsmounted on sheetmetal strips which catch under and behind theoverlaybeam and are clamped against the lower flange thereof,substantially as hereinbefore described. 7

4. A device for holding knotting-threads comprising a leaf-spring and ahook-shaped spring at each side thereof, the ends of said springs freeto move, a su port for the springs including means to detachably connectthem to a beam, substantially as described.

5. A device for holding knotting-threads, comprising a reversely-curvedsprin and hook-shaped springs at each side t ereof, l

means to support the springs comprisingga member 4 and a spring member6, substan- 2o tially as described.

6. A device for holding knotting-threads, comprising a s ring reverselycurved at its free end, a hoe -shaped spring at each side thereof, meansto support the springs com- 2 5 prising a member 4 and spring members 6formed in one piece With the hook-shaped springs, substantially asdescribedf In testimony whereof I have signed my name to thisspecification in the presence of 0 tWo subscribing Witnesses.
